Sweating
While your post-work workout or morning jog routine would enhance endorphins, these activities would also cause an outbreak of hives. The reason is that your body will produce acetylcholine, a component that would limit the breakdown of cells, to respond to these exercises. As a result, it would disrupt their skin cells and thus irritate the skin and create itchy rashes. The sweat might also increase your body heat and trigger this health issue.[2]
